I-69 at S.R. 37 / 116th Street Interchange
Hamilton County, Indiana
This INDOT project was part of an on-call design service adding an inside median northbound travel lane to I-69 from the 82nd Street Interchange through the S.R. 37/116th Street Interchange. Interchange modifications were also developed for the S.R. 37/116th Street Interchanges including added ramp and collector-distributor lanes. Ramp widths were increased to provide double left turning movements at each end of the overpass. This was developed as a “fast track” project in less than six months to meet INDOT’s immediate needs. The project provided approximately nine added lane miles fit within the existing right-of-way to address chronic congestion and delay problems along the I-69 corridor through Fishers, Indiana and within the 116th Street/S.R. 37 interchange. Improving level of service at the interchange included adding double left turn lanes and signal modernizations for the 116th Street overpass as well as added lanes to each ramp approach to receive these movements. All overhead signage was updated and/or upgraded to address traffic changes, constructed modifications, higher reflectivity standards and current MUTCD requirements. This project had two Level One Design Exceptions that received INDOT’s endorsement and Federal Highway Administration approval.
